TYPOGRAPHICAL DISTRIBUTING-MACHINE.

Original application filed October 8, 1919, Serial No. 329,339.

January 15, 1921.

T 0 aZZ whom it may concern Be it known that I, DAVID S. KENNEDY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Typographical Distributing-Machines, of which the following is a specification, reference being had therein to the accompanying drawing, being a division of an application filed by me October 8, 1919, Ser. No. 829,339.

My invention relates to typographical machines, such as linotype machines of the gen eral organization represented in Letters Patent of the United States to O. illergenthaler No. 436.532, wherein circulating matrices are released from a magazine in the order in which their characters are to appear in print and then assembled in line, the composed line transferred to the face of a slotted mold, the mold filled with molten metal to form a slug or linotype against the matrices which produce the type characters thereon, and the matrices thereafter returned through distributing mechanism to the magazine from which they started.

In the parent application Ser. No. 329,339 above noted, there is presented a machine equipped with two distinct magazine entrances differing as to the number and arrangement of their matrix channels and mounted so as to be interchangeable in p0sition with each other to cooperate with different kinds of matrix fonts or with magazines of different forms. My present invention is directed to an improved form of mounting for the two ma azine entrances, as will best be understood from the detailed description to follow.

Referring to the drawings:

Figure 1 is a side elevation of the upper portion of a linotype machine equipped with my improvements;

Fig. 2 is a rear view, at opposite sides, of the parts shown in Fig. 1, the distributer bar being omitted;

Fig. 3 is a view similar to Fig. 1, and illustrating an improved spring arrangement for holding the entrances in place; and

Fig. 4 is a section taken on the line l;t of Fig. 3.

I have herein shown only those parts of the machine immediately concerned with the Specification of Letters Patent.

Patented Nov. 22, 1921.

Divided and this application filed Serial No. 438,061.

present invention. For any further details, reference may be had to said parent application Ser. No. 329,339, which shows the machine in its entirety.

The matrices of the font or set in use are stored in the channeled magazine A and are returned thereto from the distributer C, 0 through one or the other of the two magazine entrances D and F. The magazine A is removably mounted upon the customary base frame A which latter is arranged to be swung upwardly from its normal position in effecting the removal of the magazine. In this instance, therefore, to change from one kind of matrix font to another, the magazine A containing matrices of one kind is removed from the machine and replaced by a substitute magazine containing matrices of another kind. Such an interchange of magazines involves a corresponding interchange of the .two magazine entrances, and, as before stated, the present invention is intended to provide an improved form of mounting whereby the two entrances may be quickly and readily interchanged in position with each other when required.

As shown, the entrance D is pivotally connected to the base frame A by pins D in the customary way, while the entrance F is carried by a pair of long supporting arms F attached thereto at opposite sides and formed with slots F extending throughout the length of the arms. These arms F straddle the entrance D and are arranged to rock and slide upon the pivot pins D which are extended sufficiently to engage in the slots F. In the drawings, the entrance F is shown in operative position with the pins D engaged with the upper ends of the slots F, the entrance D hanging down loosely between the supporting arms F When the latter entrance is to be used, the entrance F is turned in the direction of the arrow to the position shown by the dotted lines in Fig. 1 as provided for by the arms F which slide upon the pins D until they become engaged with the lower ends of the slots F it being noted that these slots are long enough to allow the parts to clear the entrance D, which is then swung up through the supporting arms F to operative position. This manipulation of the parts is reversed in restoring the entrance F to operative position. In

, tomary springD'r,

end to the base frame A and at its Figs. 1 and 2, the two entrances are held in operative position by means of a pair of yielding detents F mounted in the ends of a pair of rearwardly extending brackets F on the base frame A and which are adapted to engage in recesses in the sides of the entrance frames. By mounting the brackets F on the base frame A the latter is free to be rocked upwardly for the removal of the magazinewvithout disengaging the detents F from the active magazine entrance, which therefore remains in operative position on the frame.

In Figs. 3 and 4, spring devices are employed to hold the two magazine entrances in operative position. As therein shown, the entrance D has associated therewith the cuswhich is attached at one opposite end directly to the entrance. For the entrance F, there is provided a further spring F also attached at one end to the base frame A but connected at its other end to a lever F which is mounted to turn loosely on apivot pin D the latter being-formed witha head-portion to retain the lever thereon (Fig. 4:). formed near its pivot with an open notch or recess F arranged to engage a pin F rojectin laterally from the side of the entrance F, Hence, by turning the lever F about the pivot pin D the spring F may be connected to or disconnected from V the entrance F as required, this arrangement thus enabling the entrance when in use to be held in position under spring tension and when out of use to be entirely relieved of such tension. In Fig. 3, the entrance F is shown in operative position with the spring F connected thereto through the medium of the pivoted lever F With the spring so connected, the entrance'may be rocked downwardly to the dotted line position shown at the upper part of the figure to give.access to the interior parts, the spring yielding to permit this rocking movement of the entrance and acting immediately it is released to restore it to operative position. Now, when the entrance F is to be replaced in operative position by the entrance D, the lever F is first turned down to the dotted line position indicated at the lower left hand corner of Fig. 3, which movement of the lever disengages its notch F from the pin F and thus disconnects the spring F from the entrance F. The latter is then free to be slid along the pivot pins D and turned downwardly'to its 'inactiveposition' as before described. It is obvious of course that in the use of the arrangement shown inFigs. 3 and l, the base frame A is free at any time to be rocked upwardly for the removal of the magazine without disturbing the active magazine entrance which will be maintained in opera- This pivoted lever F is tive position thereon under the tension of its spring.

While in the accompanying drawings I have shown my improvements in connection with a single magazine machine, it should be understood that they are equally applicable to machines of the shiftable multiple magazine variety as well. Inshort, I have herein shown my invention merely in preferred form and by way of example, and obviously many changes and modifications may be made therein without departing from its spirit. I therefore desire it to be understood that I do not limit myself to any specific form or embodiment except in so far as such limitations are specified in the claims. I

Having thus described my invention, its construction and mode of operation, what I claim is. as follows:

1. In a typographical distributing machine, the combination of a magazine entrance permanently located in the machine and pivotally mounted therein so as to be movable into and out ofoperative position, and a substitute magazine entrance also permanently located in the machine and pivotally and slidably mounted therein so as to permit its interchange with the other entrance.

2. In a typographical distributing 1nachine, the combination of a magazine entrance permanently-located in the machine and pivotally mounted therein so as to be movable into and 'out of operative position, and a substitute magazine entrance also permanently located in the machine and provided with a pair of supporting arms spanning the other entrance and pivotally and slidably arranged so as to permit the interchange of the two entrances without interference. I

3. In a typographical distributing machine, the combination of two magazine entrances, and common pivot pins therefor, the said entrances being mounted on said pivot pins so as to be interchangeable in position with each other.

i. In a typographical distributing ma-- chine, the combination of a-magazine en trance, pivot pins whereon said entrance is 'movably mounted, and a substitute entrance trance to rockand slide on said pins.

6. In a typographical distributing machine, the combination of two magazine entrances, and common pivot pins therefor, one of said entrances being provided with supporting arms spanning the other entrance and formed with elongated slots wherein the pivot pins engage, in the manner and for the purpose described.

7. In a typographical distributing machine, the combination of a magazine entrance, and pivot pins whereon said entrance is mounted, said entrance being provided with elongated slots wherein the pivot pins engage so as to permit said entrance to rock and slide on said pivot pins.

8. In a typographical distributing machine, the combination of a magazine entrance movable into and out of operative position, a spring to hold the entrance in operative position, and means for connecting and disconnecting the spring to and from the entrance at will.

9. In a typographical distributing machine, the combination of amagazine entrance mounted so as to be movable into and out of operative position and a spring-actuated lever arranged to be engaged with and disengaged from said entrance and acting when so engaged to hold it in operative position.

10. In a typographical distributing machine, the combination of a magazine entrance pivotally mounted so as to be movable into and out of operative position, a spring for holding the entrance in operative position, and a lever to which the spring is connected, the said lever being mounted to turn on an axis coincident with that of the entrance and arranged to be engaged with or disengaged from the entrance at will.

11. In a typographical distributing machine, thc combination of a magazine entrance pivotally and slidably mounted so as to be rocked to and from operative position or shifted bodily into and out of operative position, and a spring-actuated lever arranged to be engaged with or disengaged from said entrance and acting when so engaged to permit a, rocking movement of the entrance only and when disengaged to allow the entrance to be shifted bodily, for the purpose described.
